TEMPLE ROLL Carl D. Brown,

Draper Corporation, poration of Maine Application March 10,

lv Claims.

The present invention pertains to temple rolls for loom temples and hasmore particular reference to the character and construction of thefabric-engaging surface of such rolls.

Loom temples commonly include a head hav ing one or more rotatablefabric engaging rolls which extend inwardly, widthwise of the cloth,from the cloth selvage. The cloth is pressed against the rolls and thesurface of the latter is constructed and arranged to hold the clothtaut, widthwise, as it is woven. The present invention appliesparticularly to such temple rolls wherein the surface thereof is adaptedto hold the cloth by friction, as distinguished from the pin-studdedrolls commonly used on relatively coarse cloth.

In prior constructions, the friction type of temple roll was formed fromor covered with a suitable resilient fabric-gripping material such asrubber, synthetic rubber or cork. Such materials have a high coeicientof friction with cloth and are therefore effective in holding the clothtaut. However, the resilient materials that are available for thepurpose are not very eifective in withstanding the wearing action of thecloth and the useful life of prior temple rolls using said materials iscomparatively short. The said wearing action is particularly severe ator near the selvage end of the temple roll, and is also found at theopposite or inner end of 'the roll, but is comparatively slight at thecentral portion of the roll. Thus, the temple rolls that are discardedas being worn out are badly worn at one or both ends and the centerportions are still serviceable.

An object of the present invention is to provide a temple roll of thefriction type having its central portion of a resilient fabric-grippingmaterial, for holding the cloth, and its selvage end portion constructedand arranged to effectively 40 resist wear without detracting from thegripping qualities of the central portion, whereby the useful life ofthe temple roll is materially increased.

The aforementioned and other objects of the invention are accomplishedin the construction illustrated on the accompanying drawing, of which:

Fig. 2 is a fragmentary plan view of the same temple with the capthereof broken away to eX- pose the preferred embodiment of my improvedtemple rolls therein;

Fig. 4 is a longitudinal sectional View of the temple roll of Fig. 3.

The temple shown on the drawing includes a stand or housing l which isadapted to be fixed to a loom frame (not shown) and a bar 2 which isslidably mounted in the housing. The bar 2 is positioned adjacent andsubstantially parallel to the selvage S of the cloth C and has alaterally extending head forA receiving the cloth. This head maycomprise a pod 3 and cap il for receiving my improved temple rolls, thetemple eX- cept for such rolls being of usual construction.

The pod 3 and cap 4 constitute a housing for two parallel temple rolls5, 5 which housing has the usual opening to permit the cloth to feedforwardly through the temple head in contact with the temple rolls. Therolls 5, 5 are rotatably mounted on the usual pins (not shown) which aresupported by the cap 4. The cloth C, in the particular temple shown,passes between the pod 3 and the bottom of the temple rolls, the shapeof the pod being such as to hold the cloth in contact with the rolls.

The temple rolls 5 are of the friction type in that they grip or holdthe cloth by friction only. Each such temple roll comprises a roll bodywhich is generally cylindrical in shape. In the preferred embodiment,the temple roll 5 consists of a wood core 6 having fabric-engagingcovering thereon. This covering consists of a central portion 1 ofsuitableresilient fabric-gripping material such as synthetic rubber, andend portions 8 and 9 of vulcanized ber or other relatively hardwear-resisting material. The covering eX- tends from end to end of thecore 6 except that the latter is provided at its inner end with aprojecting enlargement or head I which engages the inner end of theportion 9 and prevents the covering from being pulled off the core.

The end of the temple roll 5 on which portion 8 is situated, which isthe end close to the bar 2, is the outer or selvage end of the roll. Theselvage end of the roll is, of course, engaged by the selvage S of thecloth, which may be under more tension than the main body of the cloth.This added tension, together with the contraction of the cloth inpassing forwardly off the rolls, and possibly other factors, produces awearing action which is particularly severe adjacent the selvage end ofthe roll. It is also found that, at least under some conditions, asimilar severe wearing action occurs at the opposite or inner end of thetemple roll.

The central portion 'l of the roll covering may be formed from a tube ofsynthetic rubber of sucient length to cover substantially more than halfthe length of the core 6. The external periphery of the portion 1, whichcontacts the cloth C, may be provided with suitable projections adaptedto better grip the cloth. To this end, the portion 1 may be grooved asshown to provide projecting ribs Il. I iind that the cloth holdingproperties of the central portion of the roll are not materiallyaiTected by the character or properties of the end portions of the roll.Therefore, by making the said central or gripping portion of properlength, the roll as a whole can have sufficient grip to hold the clotheven if the end portions exert no holding action on the cloth. I am thusable to make the end portions of the rolls of a hard wear-resistingmaterial, which materials have a comparatively low coeiiicient offriction with cloth.

The inner end portion 9 consists of a short tube of hard vulcanized berwhich is positioned on the core 6 between the head l'and the inner endof the central portion 1. This end portion 9 is slightly smaller indiameter than the central portion 1, to allow the latter to becompressed by pressure of the cloth. The particular portion 9 shown issmooth, as well as being hard, and it therefore exerts little grip onthe cloth. Nevertheless, the presence of such end portion on the rollprevents the aforementioned rapid wearing of the end of the temple roll.

The selvage end portion 8 is likewise formed from a tube of vulcanizedber positioned on the core 6, to prevent wear at the selvage end of theroll. This end portion may be constructed to have some cloth holdingproperties. To this end,

the portion 8 may be tapered, as shown, the

inclined cloth-engaging surface thus formed offering some resistance toWidthwise contraction of the cloth.

It will be apparent that temple rolls constructed in accordance with thepresent invention will hold the cloth reasonably well, .and will lastseveral times as long as prior temple rolls having a resilient coveringfrom end to end thereof. In the preferred embodiment above describedthis added useful life of the rolls is obtained at a comparativelyinsignificant added cost.

Having fully disclosed the preferred embodiment of my invention, Iclaim:

l. A temple roll comprising a roll body having a central portion ofresilient fabric-gripping material and a selvage engaging end portion ofhard wear-resisting material.

2. A temple roll comprising a roll body having a central portion ofresilient fabric-gripping material and fabric-engaging end portions of ahard wear-resisting material.

3. A temple roll comprising a core having fabric-engaging coveringthereon, said covering at the central portion of the roll being of aresilient fabric-gripping material and said covering at the selvage endof the roll being of a hard wear-resisting material.

4. A temple roll comprising a tubular core having its end portionscovered with fabric-engaging members of hard wear-resisting material,the portion of said core between said members being covered withresilient fabric-gripping material and the external surface of saidresilient covering being provided With fabric engaging projections.
